Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

$cos(37)=\frac{11}{x}$

step 1 multiply each side by x

$cos(37)*x=xcos(37)\\\frac{11}{x} *x=11$

now we have $xcos(37)=11$

step 2 divide each side by cos(37)

$\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\$

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8

Answer:

c = 53 yd is the answer.

Step-by-step explanation:

a = 45 yd

b = 28 yd

c = ?

According to the Pythagorean Theorem,

a² + b² = c²

45² + 28² = c²

2025 + 784 = c²

c² = 2809

c = 53 yd

∴ The dog runs 53 yd

HELP THIS IS HARD SOMEONE pls

Answer:

3rd option

Step-by-step explanation:

Since the centre of dilatation is at the origin then multiply the coordinates by $\frac{1}{3}$

K (- 3, 9 ) → K' (- 3( $\frac{1}{3}$ ), 9( $\frac{1}{3}$ ) ) → K' (- 1, 3 )

L (- 9, 0 ) → L' (- 9( $\frac{1}{3}$ ), 0 ( $\frac{1}{3}$ ) ) → L' (- 3, 0 )

M (2, - 8 ) → M' (2 ( $\frac{1}{3}$ ), - 8 ( $\frac{1}{3}$ ) ) → M' ( $\frac{2}{3}$ , - $\frac{8}{3}$ )

N (6, 4 ) → N' (6 ( $\frac{1}{3}$ ) , 4 ( $\frac{1}{3}$ ) ) → N' ( 2, $\frac{4}{3}$ )
